Paper Abstract

In vitro research has demonstrated the ability of argon laser irradiation to reduce demineralization or loss of tooth structure. This clinical pilot study was conducted to investigate the effectiveness of this procedure in vivo. Using the Ogaard model of producing demineralization, the experimental teeth were irradiated with argon laser (primarily 488 nm and 514 nm) of 250 mW, approximately 12 J/cm2 fluence, prior to banding. Polarized light evaluation of the sectioned, extracted teeth showed reduced demineralization in the experimental teeth as compared to the bilateral control teeth. Lower powered argon laser irradiation significantly reduced demineralization clinically.
